- *  U S A G E
- * ===========
- *
- * For DES or Triple-DES encryption/decryption you must initialize a proper
- * encryption context with a key.
- *
- * A DES key is 64bit wide but only 56bits of the key are used. The remaining
- * bits are parity bits and they will _not_ checked in this implementation, but
- * simply ignored.
- *
- * For Triple-DES you could use either two 64bit keys or three 64bit keys.
- * The parity bits will _not_ checked, too.
- *
- * After initializing a context with a key you could use this context to
- * encrypt or decrypt data in 64bit blocks in Electronic Codebook Mode.
- *
- * (In the examples below the slashes at the beginning and ending of comments
- * are omited.)
- *
- * DES Example
- * -----------
- *     unsigned char key[8];
- *     unsigned char plaintext[8];
- *     unsigned char ciphertext[8];
- *     unsigned char recoverd[8];
- *     des_ctx context;
- *
- *     * Fill 'key' and 'plaintext' with some data *
- *     ....
- *
- *     * Set up the DES encryption context *
- *     des_setkey(context, key);
- *
- *     * Encrypt the plaintext *
- *     des_ecb_encrypt(context, plaintext, ciphertext);
- *
- *     * To recover the orginal plaintext from ciphertext use: *
- *     des_ecb_decrypt(context, ciphertext, recoverd);
- *
- *
- * Triple-DES Example
- * ------------------
- *     unsigned char key1[8];
- *     unsigned char key2[8];
- *     unsigned char key3[8];
- *     unsigned char plaintext[8];
- *     unsigned char ciphertext[8];
- *     unsigned char recoverd[8];
- *     tripledes_ctx context;
- *
- *     * If you would like to use two 64bit keys, fill 'key1' and'key2'
- *	 then setup the encryption context: *
- *     tripledes_set2keys(context, key1, key2);
- *
- *     * To use three 64bit keys with Triple-DES use: *
- *     tripledes_set3keys(context, key1, key2, key3);
- *
- *     * Encrypting plaintext with Triple-DES *
- *     tripledes_ecb_encrypt(context, plaintext, ciphertext);
- *
- *     * Decrypting ciphertext to recover the plaintext with Triple-DES *
- *     tripledes_ecb_decrypt(context, ciphertext, recoverd);
- *
- *
- * Selftest
- * --------
- *     char *error_msg;
- *
- *     * To perform a selftest of this DES/Triple-DES implementation use the
- *	 function selftest(). It will return an error string if there are
- *	 some problems with this library. *
- *
- *     if ( (error_msg = selftest()) )
- *     {
- *	   fprintf(stderr, "An error in the DES/Tripple-DES implementation occured: %s\n", error_msg);
- *	   abort();
- *     }
